Book this property if it is available! It is pretty central: a two minute walk to Chong Nonsi BTS, which is itself three stops to Siam Paragon. Its a large, stylish (the style vintage is more 1970 than modern, which is really cool), well-kept and well-provided property. It is everything you can ask for and more.
Please make sure you have understood the location before you arrive, for the Google Maps misleads you and we had to go round and round for some time.
